A freind of mine used to have a breeding pair of GTP's. He would sale the babies for about $300 a peice wholesale, so I'd say you got one hell of a deal.
Also about the bigger cages. My freind said the problem with the large cages with the babies, is they needed extremely high humidty, and most people wouldn't keep the humidity high enough in a large cage. Don't know if thats true, but just what he told me.
BTW after getting back from vacation a couple of weeks ago, I contacted bobclark about a pair of rainbows. They wont have any more for a couple of more months. They said they contact us when their ready to go.
